Comprehensive Water Treatment System which exceeds our minimum water requirements. Proof of installation and proper cartridges replacement is required for

warranty coverage. Water supply to Crown Steam Group steamers must be within these guidelines.

Water which does not meet these standards should be treated with the installation of Middleby’s Water Treatment System. Call 919-762-1000 if you have

questions concerning your water meeting these parameters.

*Failure or malfunction of this appliance due to poor water quality is not covered under warranty.

1. The Serial and Rating Plate on the unit indicates the type of gas your unit is equipped to burn. DO NOT connect to

any other gas type.

2. A 3/4” NPT line is provided at rear for the connection. Each compartment is equipped with an internal pressure

regulator which is set at 3.5” W.C. manifold pressure for natural gas and 10” W.C. for propane gas. Use 1/8” pipe tap

on the burner manifold for checking pressure.

An adequate gas supply is imperative. Undersized or low pressure lines will restrict the volume of gas required for

satisfactory performance. A steady supply pressure, between 6” W.C. and 14” W.C. for natural gas and 12” W.C. and

14” W.C. for propane gas is recommended. With all units operating simultaneously, the manifold pressure on all units

should not show any appreciable drop. Fluctuations of more that 25% on natural gas and 10% on propane gas will create

The steamer is equipped with a cold water condenser, in the rear of the cooking chamber, which helps to condense the

steam prior to discharge into the drain. The steamer freely vents itself by the negative pressure created by the condensate

water drainage. This negative pressure prevents steam leakage around the door gasket and helps draw the steam

through the cooking compartment. Steam leakage at the door may indicate a plugged or improperly installed drain.

It is important that the water supplied to the generator be softened to no more than 2.0 grains of hardness and have a pH

of 6 to 7.5. This degree of hardness can be easily obtained with the use of a properly maintained water softener. The use

of a water meter will determine the water consumption and when the water softener needs regeneration or recharging.

Failure to comply with these water condition standards may void the warranty.

Untreated water contains scale producing minerals which can precipitate onto the surfaces in the steam generator. Due

to the temperatures in the steam generator, the minerals can bake onto the surfaces and components. This can result in

early component failure and reduced product life. Water level probes become coated with scale. Scale may bridge across

the probe insulator from the metal extension which senses the water level in the steam generator shell. Once this scale

becomes wet, the water level control is unable to maintain the proper water level in the steam generator.

STRAINERS and FILTERS will NOT remove minerals from the water.

CAUTION

The appliance and its parts are hot. Use care when operating, cleaning and servicing the appliance.

Once the steamer is installed and all mechanical connections have been made, thoroughly test the steamer before

operation.

1. Check that proper water, drain and electrical and gas connections have been made.

2. Turn main power switch ON.

3. Check that “Ignition” light comes on when the pilot burner is on.

4. After approximately 15 minutes, the “READY” light should come on, indicating that the water temperature is 205º

Fahrenheit (97º Celsius). When the “READY” light comes on, set timer to the “5 minute” position. With door open,

observe that no steam is entering the compartment and that the “COOKING” light is OFF.

5. Close compartment door. The COOKING light should now illuminate and steam should be heard entering the

compartment after about 45 seconds.

Frequently check that the compartment drain and plumbing is free of all obstructions. Never place food containers, food or

food portion bags in the cooking compartment in such a way that the compartment drain becomes obstructed.

WARNING

When this appliance is installed with casters and is connected to the supply piping by means of a connector for

moveable appliances, a restraint to prevent damage to the connector or quick disconnect device should have

been installed. If disconnection of the restraint is necessary, reconnect this restraint after the appliance has been

returned to its originally installed position.

IMPORTANT

Each compartment is equipped with a removable drain screen. Frequently check the drain screen for accumulation

of food particles. Should food particles accumulate against, or clog the drain screen, remove it, clean it thoroughly

and then replace it in its original position.

CONTROLS

cook only enough to start serving, then cook additional amounts to meet demand. Separate frozen foods into smaller

Use a pan cover for pre-cooked frozen dishes that cannot be cooked in the covered containers in which they are packed

if they require more than 15 minutes of cooking time. When cover is used, approximately one-third additional cooking time

is necessary.

Cooking time for frozen foods depends on amount of defrosting required. If time permits, allow frozen foods to partially

thaw overnight in a refrigerator. This will reduce their cooking time.

P

Prepare vegetables, fruits, meats, seafood and poultry normally by cleaning, separating, cutting, removing stems, etc.

Cook root vegetables in a perforated pan unless juices are being saved. Liquids can be collected in a solid 12” x 20” pan

placed under a perforated pan. Perforated pans are used for frankfurters, wieners and similar items when juices do not

need to be preserved. Solid pans are good for cooking puddings, rice and hot breakfast cereals. Vegetables and fruits

are cooked in solid pans in their own juices. Meats and poultry are cooked in solid pans to preserve their own juices or to

retain broth. Canned foods can be heated in their opened cans (cans placed in 12” x 20” solid pans) or the contents may

be poured into solid pans.

P

The steamer compartment is designed to accept combinations of 12 inches x 20 inches pans (either solid or perforated).

At the end of each day, or between cooking cycles if necessary:

1. Turn main power switch OFF.

2. Remove pans and racks from compartment and wash in sink.

3. Wash compartment interior with clean water.

4. Use warm soapy water with a cloth or sponge to clean exposed bead of door gasket, rinse with warm clear water and

wipe with a dry cloth.

Wipe surfaces which touch door gasket with a cloth or sponge and warm soapy water, rinse with warm clear water

and wipe with a dry cloth. Do not apply food oils or petroleum solvents or lubricants directly to door gasket or surfaces

which touch door gasket.

5. Wipe all solids away from drain opening in compartments to prevent clogging.

Keep cooking compartment drain working freely. After cooking grease producing foods, operate steam with

compartment empty for 30 minutes at end of the day, or pour ½ gallon of warm soapy water down the drain, followed

by 1/2 gallon of warm clear water.

6. Leave door slightly open when steamer is not in use.

It is NOT RECOMMENDED to use cleaning agents that are corrosive.

Use of cleaning agents that contain chloride, acids or salts which are corrosive may cause pitting and corrosion when

used over a period of time; this will reduce the life of the appliance.

Should pitting or corrosion occur, this is not covered by the warranty.

Follow the recommended cleaning instructions. Use a mild detergent, warm water and rinse thoroughly.

Never spray water into electric controls.

Following daily and period maintenance procedures will enhance the long-life for your equipment. Climactic conditions -

Darkened areas sometimes appear on the stainless steel surface where the area has been subjected to excessive heat.

These darkened areas are caused by thickening of the protective surface of the stainless steel and are not harmful. Heat

tint can normally be removed by the foregoing, but tint which does not respond to this procedure calls for a vigorous

scouring in the direction of the polish lines using SCOTCH-BRITE scouring pads or a STAINLESS scouring pad in

combination with a powdered cleanser. Heat tint action may be lessened by not applying or by reducing heat to equipment

during slack periods.
